Abstract: A method, system, and computer program product for controlling data packet traffic flow into a link partner device such as an ethernet adapter. In one embodiment, an occupancy level of an adapter receive queue is monitored to detect a receive queue overrun or underrun condition or event. The detected overrun or underrun condition or event is utilized as the criteria for adjusting a pause time value within a pause time flow control frame. The pause time flow control frame is transmitted from the link partner device to a corresponding remote link partner device to pause data packet transmission in accordance with the adjusted pause time value.

Abstract: A sending device prepares a key for each electronic message sent by the device by applying an algorithm to specified data in the message and then incorporates the key in the message. A receiving device, upon receipt of an electronic message, locates the incorporated key and the data from which a sending device practicing the invention would have prepared it. The receiving device communicates a confirmation request to the purported sending device which contains the key and the data for its preparation. The sending device receives the confirmation messages and prepares a comparison key by applying the algorithm to the data in the confirmation request. The sending device replies to the confirmation request confirming that the sending device sent the message if the comparison key matches the key in the confirmation request and otherwise responds with a denial.

Abstract: Where parallel links between network devices are aggregated into link groups to support the transport of associated data streams, the link groups can be managed in an energy efficient manner by defining each link group as consisting of a primary link and one or more secondary links. The primary link in a link group remains enabled at all times but the secondary links are enabled only when needed and are disabled when no longer needed, minimizing power consumption for the secondary links (and the link group).

Abstract: A cabinet having a pair of vertically stacked chassis separated by a central, vertically extending region. A pair of laterally spaced, vertically extending panels is disposed in the central region, the panels forming: a pair of outer compartments for receiving air exiting a corresponding one of the pair of laterally spaced vertically stacked chassis; and an inner compartment for receiving air exiting the pair of vertically stacked chassis. The panels have therein an array of openings in a lower portion thereof for passing portions of air in the outer compartments into the inner compartment. An upper portion of the panels inhibits portions of air in the outer compartments from passing into the inner compartment. The openings extend in rows horizontally across the panel. The number of opening in lower ones of the rows is greater than the number of opening in upper ones of the rows.

Abstract: A computer implemented method and apparatus are provided for transferring data in a logical partitioned data processing system. A receiving adapter receives data from a network. The receiving adapter transfers the data to a pre-mapped buffer if the data is to be sent to a target adapter. A virtual bridge receives the pre-mapped buffer from the receiving adapter and transfers the pre-mapped buffer to the target adapter. The target adapter receives the pre-mapped buffer from the virtual bridge and determines that the received buffer is pre-mapped. The target adapter accesses the pre-mapped buffer using pre-mapped mapping, and transmits the data contained therein.

Abstract: Performing high-resolution determination of the relative shift of the spectral properties of a biosensor. The shift in the resonance peak of the biosensor is indicative of the amount of material bound to the surface of the biosensor. A preferred biosensor is a Guided Mode Resonant Filter Biosensor (GMRFB). In one aspect of the invention, curve fitting is used to determine the relative location of the spectrum of the unexposed biosensor with respect to those spectra that are altered (e.g., shifted) by the presence of materials bound to the surface of the biosensor. In an alternative embodiment, the cross correlation function is used to detect spectral peak offsets between a reference spectrum and a spectrum measured from an exposed biosensor. In yet another alternative, maximal likelihood estimation techniques are used to determine the spectral shift or offs.

Abstract: A method, system, and computer program product for circumventing data copy operations in a virtual network environment. The method includes copying a data packet from a user space to a first kernel space of a first logical partition (LPAR). Using a hypervisor, a mapped address of a receiving virtual Ethernet driver in a second LPAR is requested. The first mapped address is associated with a buffer of the receiving virtual Ethernet driver. The data packet is copied directly from the first kernel space of the first LPAR to a destination in a second kernel space of the second LPAR. The destination is determined utilizing the mapped address. The direct copying to the destination bypasses (i) a data packet copy operation from the first kernel space to a transmitting virtual Ethernet driver of the first LPAR, and (ii) a data packet copy operation via the hypervisor. The receiving virtual Ethernet driver is notified that the data packet has been successfully copied to the destination in the second LPAR.

Abstract: A computer implemented method and data processing system for the detection and recovery of a network interface card TCP acceleration offload failure. Responsive to a failure to receive an acknowledgement of a transmission control protocol segment containing a request for a transmission control protocol offload function in a network interface card, the transmission control protocol segment is retransmitted without the request for a transmission control protocol offload function. When an acknowledgement of the retransmitted transmission control protocol segment without the request for a transmission control protocol offload function is received, a counter is incremented which indicates a failure of the transmission control protocol offload function. Responsive to the counter exceeding a predefined number of allowed failures, all requests to the transmission control protocol offload function for the network interface card are stopped.

Abstract: The present invention provides a computer implemented method and apparatus for allocating communication buffers in a data processing system. The method comprises a streamlined mbuf pool service receiving a call from an I/O device driver, then determining if at least one mbuf linked list is empty. In response to a determination that at least one mbuf linked list is empty, the streamlined mbuf pool service calls an OS mbuf allocator to provide all mbufs in a second mbuf linked list, wherein the second mbuf linked list comprises a head of the second mbuf linked list. The streamlined mbuf pool service repopulates the second mbuf linked list, obtains a requested mbuf from the second mbuf linked list, and advances the head of the second mbuf linked list by at least one mbuf. The streamlined mbuf pool service then returns the requested mbuf to the I/O device driver, wherein the OS mbuf allocator allocates all mbufs in the second mbuf linked list.

Abstract: A bezel has a locking mechanism that allows bezel designs to locate the bezel lock anywhere along the length of the bezel. The bezel includes a bezel frame, a first plunger mechanism, and a second plunger mechanism. Each plunger mechanism is moveably coupled to the bezel frame at opposite ends of the bezel frame and is movable between a latched position and an unlatched position. A first rod is attached to the first plunger mechanism and a second rod is attached to the second plunger mechanism. A cam lock is positioned between the first rod and the second rod. The cam lock is movable between a locked position and an unlocked position, wherein the cam lock restricts movement of both rods sufficiently to stop the plunger mechanisms from moving from the latched position to the unlatched position when the cam lock is in the locked position.
